Design module with the Coandă e ect - EFFETTO Design module with the Coandă e ect EFFETTO Comfort and design in perfect harmony Galletti introduces EFFETTO, the design module for air intake and diffusion designed to complement the reliability and comfort of ACQVARIA and ACQVARIA i hydronic cassette units (600x600 mm model). EFFETTO breaks with standard hydronic cassette units, going far beyond the classic ABS grille with adjustable fins, and presents a design module that takes advantage of the Coandă effect. Galletti's Advanced Design Unit has created an Italian-made hydronic cassette unit with a minimalist, streamlined design that can be incorporated into the style of any space, even in terms of colour. EFFETTO is not just about aesthetics but also comfort, as it has been designed to optimise air diffusion thanks to the Coandă effect. EFFETTO’s Dibond metal panel is comprised of a sandwich of aluminium and polyethylene. The fine metallic finish is combined with the insulating properties of polyethylene to prevent condensation. The steel intake grille creates a single surface with the panel, thus enhancing the overall subtlety of the product. The filter can be easily removed for maintenance operations. The air duct is made of black RAL 9005 polystyrene for a perfect colour match, and its geometry is designed to optimise the air flow in the room. The brightness of the aluminium allows the grille to adapt to any situation, while keeping the milled edge of the panel, which outlines its shape, clearly visible, even in low light conditions. The module, detached from the ceiling, interacts with all the elements and light sources in the room. EFFETTO is the perfect choice to ensure a smooth, streamlined appearance to the space to be air-conditioned. AVAILABLE VERSIONS Three colour versions are available: brushed natural aluminium, white RAL 9010, and black RAL 9005. Black is also used for all the components of the internal and technological structure in order to create a shadow effect on the surrounding surfaces, making the panel appear to float in the air.

COMPUTATIONAL FLUID DYNAMICS SIMULATIONS AIR DUCT Computational uid dynamics (CFD) simulations have made it possible to study the di usion of air in interiors in order to make the most of the Coandă e ect: the air ow reaches the ceiling without passing directly over the occupant, thus preventing localised discomfort.

Design module with the Coandă e ect - EFFETTO EFFETTO AIRCLISSI Often hydronic indoor units are evaluated on the basis of a single criterion: their technical performance. Undoubtedly, thermodynamic and acoustic performance are very important, but only if they are part of a broader comprehensive concept. Today, the hydronic indoor unit must be considered equally with all the other furnishings in the space to be air-conditioned: a platform capable of interacting with the layout of the environment and the people who live in it. This interaction is now even stronger, with a novel emotional...
